4 SPECIFICATION" forming part of Letters Patent No. 244,822, dated July26, 1881.

' v 4 Application tiled November 22, 1880. (No model.)

To all whom it may concern:

Be it known that I, ALBERT S. ROBINSON, of the city and county ofAlbany, and State of 'N ew York,have invented certain new andusedi'erentsizes and, third, to prevent the niaterial that'is forced into thepressing-chamber by the plunger of the machine from being vretractedtherefrom by the return movement ot' the plunger. -These objects I'attain by the mechanism illustrated in the accompanying drawings, whichform a part of this specification, and in whichy v Figure 1 is asideelevation of my press, with portions of the side broken away fr-thepurpose of showing the underlying parts;` Fig. 2, a plan view; Fig. 3,va vdetached sectional view of the end of the press, showingthegear-wheels not shown in Fig. l; Fig-4, an

enlarged transverse section, at the line w :10,of`

ton-diagrams of the gear-wheels for operat-v ing the doubletoggle-joints.

As represented in the drawings, a is the,-

press-box, made in a rectangular form,having a pressing'chamber, A,inwhich the material is compressed directly behind it, and a rearwardextension, formingthe baling-chamber A2, (corresponding in size andshape to the transverse'section of the pressing-cl1amber A,) providedwith a close top and bottom, but whose sides are simply provided withthe top and bottom guiding-strips a, whereby the bales are guidedthrough the chamber, and the opening A4 is formed to facilitate theoperation of tying oft' the compressed bale while in thebilling-chamber. Aforward extension, A3, is attached to the press-box Afor forming a framing for receiving the mechanism for actuatin g thecompressing lnechanism.

B is a plunger tted to slide freely in the press-box A, and having fixedthereto a rod, b, that is guided by the cross-piece a. A crosshead, b',is secured to the outer end of the rod b for receiving the inner ends ofthe plungermoving mechanism. Said mechanism consists of duplextoggle-joints-an upper one, O, and 6o lower one,D-so arranged that whenthe parts are'extended to force the plunger to the eX- tremity of itsstroke into the pressing-chamber the knuckles c and d will lie at theirnearest approach to a central line,from which line the said knucklesmove outward in` opposite directions until they attain the positionsshown in Figsl and 3, when the plungeris drawn backward to the otherextremity of its stroke. The inner ends of the toggle-joints are pivotedby 7o the pins c and d', to the cross-head b', and their outer ends arepivoted in a like manner to the cross-piece a2 by the pins c2 and d2.

f Motion is imparted to the toggle-joints by means of the gearedcrank-wheels E and F, 7 5 whosecenters of rotation are independent'ofeach other, but ranged in the same continuous line, so that the disks ofthe wheels will face each other from the opposite side of the press, thewheel E being connected by the pitman e 8o to the upper toggle-joint, C,and the wheel F bythe pitmanf to the lower toggle-joint, D. The wheels Eand F are uniform in size,- and are arranged to rotate isochrononsly,but in opposite directions, as indicated by the diagrams, Figs. 6 and 7,tllisuniformity ot speed but opposition in movement being necessary toproduce the motions ot' the duplex togglejoints in opposite directions.Motion is imparted to the wheels E and F by a driving- 9o shaft, Gr,through trains ot' gearing, (indicated by the skeleton-diagrams in Figs.6 and 7.) In Fig. 6 the wheel Eis shown as rotating in the samedirection as the driving-shaft, and to et'- fect this the said shaft hassecured to it a pinion, g, that gears into a wheel, H, secured to theshaft h', which is also provided with a pinion, h, that gears into thewheel E. In Fig. 7 the wheel F is shown as rotating in an oppositedirection to the driving-shaft. rIhis is roo eected by means of apinionyi, secured to the shaft G and gearing into a pinion, fi', ot' thesame size, that gears into the wheel J, secured to the shaft j', whichalso carries the pinion j, that gears into the wheel F. The gear-wheelsH and J and pinions g, i, and i are contained between the platesattached to the framing of the forward extension, A, and the positionsof said wheels are indicated by the dotted lines in Figs. l and 3.

K is a hopper fixed on the top of the machine, through which thematerial is fed into the prcssbox A. At the rear end of the opening forsaid hopper there is placed a roller, L, provided with longitudinalgrooves of angular form, whose deepest incisions are formed by radiallines. Secured to one end of said roller there is a ratchetwheel, Z,into which a pawl, l', engages to prevent the roller from turningbackward. Said roller rotates in bearin gs adapted to move verticallyagainst the resistance of springs l2. A second roller, L', of likeconstruction, and provided with the same appliances that are attached tothe roller L, is placed in the bottoni of the press-box directlyopposite the roller L. Both rollers are arranged so that the beveledside of the grooves lying toward the inside of the press-box will befaced toward the inner end of the plunger B. By this arrangementtherollers are adapted to yield outwardly and to rotate on theirbearings when an excessive quantity of material is carried forward bythe plunger. A guard, M, is placed over the roller L, inside of thehopper K, to prevent the material,as it is fed into the press-box, fromclogging said roller.

The sides of the pressbox A and balingchamber A4 are adapted to beadjusted sidewise, for the purpose of making bales of dilferent widths.'lo effect this purpose there are attached to the top and bottoni of thepress the bosses N, having a hole at each end tapped to receive thescrews 0, that have bearings, in which they rotate, fixed to thelongitudinal frame-timbers of the press. Said screws are provided attheir outer ends with miter-wheels P, which engage with like wheels P',secured to the vertical shafts Q at the sides of the press. On the upperend of each of said shafts there is a head, q, for receiving a crank orother suitable appliance, by which the shaft may be rotated to turn thescrews connected thereto, so as to move the sides of the press out orin, as occasion may require, and the top and bottom girts, R, areprovided with slotted openings for the tie-bolts i', so as to allow forthe adjustment above described. When the press-box and baling-chamberare widened, as described, filling-in pieces T are inserted in the topand bottom of the press, and cheekpieces b2 are secured to the sides ofthe plunger B, so that these several parts will conform in size to eachother.

I claim as my inventionl. In a baling-press, the combination, with theduplex toggle-joints C and D,ot` the crankwheels E and F, secured toseparate and independent shat'ts,whose centers arc ranged in acontinuous line that is common to both, said wheels being arranged torotate synchronously in opposite directions and connected to saidtoggle-joints in the manner described, so that each revolution of saidwheels will produce a complete movement of the toggle -joints to movethe plunger B through both phases of its reciprocating movement, asherein specified 2. In a baling-press, the baling-chamber A,V

provided at two of its oppositelylocated vertical sides with a singleopening, A4, and guiding-strips a, for the purpose of facilitating theoperation of tying oft' the bale before it is ejected from the press, asherein specified.

3. In a Daling-press, the combination, with the pressing-chamber A', ofthe balingehamber A2, arranged in relation to the pressingchamber asherein described, and provided at each of its vertical sides with asingle opening, A4, and top and bottom guiding-strips, a, as and for thepurpose herein specified.

4. The rollers L, provided with angularlongitudinal grooves, as hereindescribed, and having the ratchet l and pawl l', the said roller beingadapted to rotate in yielding bearings, and arranged in relation to thehopper lr, as herein specified.

5. A Daling-press provided with adjustable pressing and baling chamberand an adjustable plunger, whereby the press is adapted to produce balesof different widths, as herein specified.

ALBERT S. ROBINSON.
